Material and MethodsRA Rabbit Model group: 15 early RA rabbits of the same weight and variety Control group:10 normal rabbits of the same weight and varietyMethods of making RA rabbit model:elect 15 normal rabbits of the same weight and variety, dissolve Ovalbumin in 0.9% sodium chloride solution, to make the solution of 20mg/ml concengtration, blend the same quantity of complete Freund′s Adjuvant equably ,inject the mixed solution into endermic tissue of the rabbit′s scapular section, making the rabbits allergic, inject 1 ml of the mixed solution to one rabbit every time, inject 1 ml of the mixed solution in 5 different places of the rabbit′s scapular section, inject the rabbit one time every week,inject 3 weeks continuously,it turned out to be that the rabbits will be allergic, inject Ovalbumin blent with the 0.9% sodium chloride solution into the knee joint cavity of the rabbits in the fourth week, 5 mg Ovalbumin every knee joint cavity,two knees of every rabbit of the 15 rabbits are both injected,the arthrosis diameter and the exterior temperature of the knees will be added obviously in 24 hours,and they will drop gradually,at the time of the 14th or 21th day, the arthrosis diameter and the exterior temperature of the knees will get to the balance time,the incidence rate of RA is 100%.after the RA model succeeds,it is the early time of RA from the first week to the fourth week,after the fourth week,it is the late time of RA, the cartilage of the femoral condyle and the subchondral bone cortices will be changed unrecoverily.

资料与方法RA模型组：早期RA家兔模型15只，品种及体重接近。对照组：正常家兔10只，品种及体重接近。RA家兔模型制作方法：选取15只成年家兔，体重、品种接近，将卵蛋白溶解于生理盐水，配成浓度为20mg/ml的溶液，与等量完全弗氏佐剂混匀，注入家兔肩胛区皮下致敏，每只家兔每次注射1ml，于肩胛区5个不同区域注射，每周一次，连续注射3周而致敏，第4周向膝关节腔注射卵蛋白生理盐水溶液，每只关节腔注射5mg卵蛋白，15只家兔膝关节全部注射，24h内此关节直径和表面温度大幅度上升，以后缓慢下降，至14～21d达到平台期，发病率达100%。造模成功后第1～4周为早期改变，第4周以后出现不可逆的关节软骨及骨破坏。采用高频超声对RA模型组与对照组的膝关节髌上囊液体厚度、滑膜及股骨髁软骨厚度及软骨下骨皮质的回声情况进行对比观察。结果RA组模型组膝关节髌上囊积液及滑膜的厚度明显厚于对照组，其股骨髁软骨的厚度与对照组相比无明显差异，其软骨下骨皮质与对照组相比无明显改变。

The experiment results showed that at the beginning of diapause, some inhibition existed in the metabolism of converting glycogen to sorbitol and glycerol in the artificially synthesized hormone induced diapause eggs and it led to increment of trehalose, sorbitol and glycerol in the eggs and advancement of diapause termination in them. As a result, some eggs could not complete fetation and died before hatching.

试验结果表明，合成滞育激素诱导形成的滞育卵在滞育初期糖原向山梨醇和甘油的代谢反应中存在某种障碍，使卵内海藻糖、山梨醇和甘油含量减少，蚕卵滞育不深，滞育提前解除，以致胚胎发育中能量供应不足，部分卵不能完成胚胎发育而在孵化前死亡。

Chrysopa septempunctata was fed with two foodstuffs, aphids and artificial ovum Trichogramma's pupas. The results indicated that survival time of female worms which intook aphids was obviously longer compared with those which intook artificial ovum Trichogramma's pupas, and their ovum quantity obviously rose. But artificial ovum Trichogramma's pupas can be used as supplementary foodstuff to raise green lacewing because of its factory production.

用蚜虫和人工卵赤眼蜂蛹两种食料来饲养大草蛉的结果表明，喂食蚜虫的大草蛉雌成虫存活时间明显长于喂食人工卵赤眼蜂蛹的大草蛉，产卵量亦明显提高，但人工卵赤眼蜂蛹已经实现了工厂化生产，可以作为饲养草蛉的补充食料。

Because the signaling molecules RAS and ERK1/2 (extracellular signal–regulated kinases 1 and 2) are activated by an LH surge in granulosa cells of preovulatory follicles, we disrupted Erk1/2 in mouse granulosa cells and provide in vivo evidence that these kinases are necessary for LH-induced oocyte resumption of meiosis, ovulation, and luteinization.

研究人员仍然在试图解析接着发生的那些导致排卵（或在某些情况下没有排卵）的分子信号级联反应。研究人员现在证明，激酶ERK1和ERK2是该激素信号的至关重要的下游标靶。在那些颗粒细胞中缺乏这些酶的雌性小鼠中，其卵母细胞不会成熟，因而不会从它们的滤泡中释放出来。

The invention discloses a method for cultivating river crab, comprising the following steps: choosing China crab as parent crab, temporary culturing female and male crab separately, then mating; culturing the crab with ovum at temperature under 5 Deg C for more than 2 months; the crab with ovum producing out ovum and the ovum growing into flea larval, megalops larva, young crab, crab strain and adult crab.

本发明是河蟹的养殖方法，包括以下步骤：选择长江系中华绒螯蟹为亲蟹，将雌雄亲蟹分开进行暂养后，进行交配；对抱卵蟹在水温5℃以下饲养2个月以上；抱卵蟹产出卵，生成蚤状幼体，长成大眼幼体；在经仔蟹，长成幼蟹、蟹种再到成蟹。

Studies on mouse nuclear transfer with compacted morula blastomeres as donors In this study, C57BL/6 mouse morulae blastomeres and Kunming white mouse MⅡoocytes were used as donors and recipients, respectively, to investigate the effects of different sucrose concentration on the manipulation time of nuclear transfer, and the in vitro development of reconstructed embryos.

Partial or complete removal of cumulus before fertilization had no effect on fertilization rates of oocytes, but complete removal of cumulus impaired embryo development, leading to reduced morula/blastula rates.

受精前去掉山羊卵丘或者去掉部分卵丘对受精率没有显著影响，但是受精前完全去掉卵丘对于胚胎的后续发育有明显影响。

METHODS: Virginal and multiparous rabbits were superovulated by folliclestimulating hormone at different concentrations. After being obtained, the mature oocytes were activated by electric current with different strength.
